Adult dry kibble that combines weight management with joint support in a single formula. Hill's Science Diet Perfect Weight + Joint Support is designed for adult dogs carrying excess weight that also need help maintaining mobility — a pairing that's common in middle-aged, neutered, or less active dogs across all breed sizes.

The formula supports lean muscle maintenance while reducing overall calorie intake for gradual weight loss. Fish oil provides EPA, an omega-3 fatty acid that directly supports joint function — relevant because excess body weight and declining joint health often compound one another in adult dogs. Clinically tested antioxidants are included for immune support. Hill's developed this formula specifically around the nutritional biology of overweight adult dogs.

Dogs already on weight management food that are also showing early signs of joint stiffness are the natural fit here. Owners appreciate not needing two separate products for two related problems, and the clinical weight loss data gives this formula more credibility than most light kibbles.
